The idea of the game is to hit someone below the knee with the ball.
You are not allowed to pick up the ball, only to hit it with your hand.
Once you have touched it once, someone else must touch it before you can hit it again.
If the ball goes above waist height and someone catches it, the person who knocked the ball up is out.
You are not allowed to drag the ball or to pick it up.
You are out if you touch the ball twice in a row.
No kneeling on the floor is allowed.
If you are hit - go to "jail". This has only 5 spaces so when jail is full, the new "prisoner" bumps out the 1st back into the game.
